6. What is the name of the new Indian-made material that ISRO has tested for the nozzle divergent of the PSLV fourth stage (PS4)?
[A] Stellite
[B] Ramtell
[C] Litellite
[D] Sandrollite
Correct Answer: A [Stellite]
Notes:
The Indian Space Research Organisation (ISRO) has recently conducted successful tests on a new domestically produced material for the nozzle divergent of the PSLV’s fourth stage (PS4). This new material, known as Stellite (KC20WN), is a cobalt-based alloy developed in India. This advancement is a significant move towards achieving self-sufficiency in India’s space program. The final hot test took place on April 8, 2025, at the ISRO Propulsion Complex in Mahendragiri, lasting 665 seconds. In total, three hot tests were performed on two hardware units as part of the qualification process. The nozzle divergent is the wider section of a rocket nozzle that enhances gas flow speed and efficiency, thereby increasing thrust. It is part of a Convergent-Divergent (CD) nozzle system: the convergent section narrows to boost speed and lower pressure, the throat is the narrowest point where gas reaches sonic speed (Mach 1), and the divergent section expands to accelerate gas to supersonic speeds, providing additional thrust. ISRO has identified Stellite (KC20WN) as a cost-effective substitute, capable of withstanding temperatures up to 1150°C, making it suitable for high-temperature environments. This change could lead to a 90% reduction in costs related to imported materials.
7. Which NASA’s spacecraft captured the first-ever view of asteroid Donaldjohanson on April 20, 2025?

Correct Answer: C [Lucy]
Notes:
NASA’s Lucy spacecraft has achieved a historic milestone by capturing its first image of asteroid Donaldjohanson on April 20, 2025. According to NASA, the spacecraft came within approximately 600 miles (960 km) of the asteroid. This flyby is a significant event in Lucy’s 12-year mission to investigate ancient asteroids. Located 139 million miles from Earth, Donaldjohanson is situated in the asteroid belt between Mars and Jupiter. During this flyby, Lucy will collect essential data regarding the asteroid’s size and shape. Launched in 2021, Lucy’s main goal is to study primitive asteroids that have been around since the solar system’s inception. These asteroids act as time capsules, providing crucial insights into the early conditions that shaped the planets. The spacecraft is named after the renowned “Lucy” fossil, a key find in the study of human evolution. The upcoming flyby of Donaldjohanson will also serve as a practice run for Lucy’s future missions to Trojan asteroids near Jupiter, allowing it to test its scientific instruments and gather initial data. The asteroid is thought to have a distinctive shape, potentially resembling a bowling pin or a snowman, which will be closely analyzed during the flyby.

ISRO’s Axiom-4 mission will send Indian astronaut Shubhanshu Shukla to the ISS for a 14-day stay, where he will work on the Voyager Tardigrades project. Next month, India, Poland, and Hungary will launch their first government-sponsored human spaceflight mission in over 40 years. The Axiom Mission 4 will include a crew of four, featuring an American astronaut. During their two weeks at the International Space Station (ISS), they will carry out various scientific experiments. One key project is the Voyager Tardigrades, organized by the Indian Space Research Organisation (ISRO). Tardigrades, also known as “water bears,” are tiny eight-legged organisms that range from 0.1 mm to 0.5 mm in size. These hardy creatures can survive in extreme environments, including the vacuum of space, high radiation, and extreme temperatures. They have been around for about 600 million years, and their resilience makes them important for scientific studies. The Voyager Tardigrades experiment is one of seven ISRO studies at the ISS, focusing on reviving dormant tardigrades in microgravity. It will also examine reproduction by observing eggs laid and hatched in space, as well as comparing gene expression between tardigrades grown in space and those on Earth.
